MACHINE FOR FORMING AND BAILING PAPER FAILS.

Specification of Letters Patent.

Application filed May 3, 1911.

Patented Sept. 10, 1912. Serial No. 624,812.

To all whom itmoy concern: I [Be it known that I, HARRY-A. INMAN,

a citizen of the United States, residing at.

The invention relates to .such improve-- ments and consists of the novelconstruc-- tion and combination of parts hereinafter described andsubsequently claimed.

Reference may be had to the accompany.- ing drawings, and the referencecharacters marked thereon, which form a part of this specification.Similar characters refer to similar'parts in the several figurestherein. Figure l of the drawings is a view in front elevation of myimproved paper-pailforming-and-bailing machine. Fig. 2 1s a sideelevation of the same. Fig. 3 1s a horizontal cross-section of the sametaken on the broken line 33 in Fig. 2, showing in top plan the bed-plateof the machine and certaln of theoperating-mechanisms. Fig. 4 is ahorizontal section taken on the broken line H in Fig. 2, and showing inbottom plan the bed-plate and various link-and lever-connections mountedupon the underside thereof. Fig. 5 is a view in front elevation of theparts shown in Fig. 4. Fig.

Flg. 8 1s ahorizontal cross-section taken through the partly formed pail and theforming-mechanism. 9 is a similar view showing the folding operationcompleted and thebailends .driven' through the side-wings preparatory toclenching said ends. Fig. 10 is a similar view partly broken away,showing the bail-end clenched.- Fig. 11 is a plan view of the blank fromwhich the pail is fbrmed.

This invention relates more particularly to a machine for automaticallyfolding, and attaching bails to, paper-pails, such as the ordinary paperoyster-pail.

Certain objects of the invention. are toautomatically form or fold sucha pail from a blank of paper-board previously cut to the proper out lineand creasedalong the proper fold-lines; to automatically attach to sucha folded pail a wire bail, by which the same can be carried; and toprovide such a pail with a wire bail, the ends-of which are not exposedon the interior of the pail.

Other objects; will appear in connection withthe followin descrlption.

Referring to tie drawings wherein the invention is shown in preferredform, 1, represents the base of the machine and, 2, a-bed-plate or tablefixedly mounted thereon and adapted to support the blank, 3,

(shown in Fig. 11') preliminary to the folding operation, and tocooperate with the other mechanisms'in folding the blank to properform.. The bed is provided with an aperture, '4, down through which theblank is adapted to be forcedby a head or plunger, 5, verticallyreciprocatory in slideways.

in an overhanging arm, 6, erected from the base of the machine. Ayielding bed, 7, is supported by means of a spring-post, 8, withintheopening, 4, in the bed-plate in line with the plunger-head, 5, saidyielding bed being adapted to support the central part of the blankwhich forms the bottom of the pail, and which. is held clamped betweensaid yielding bed and the plunger-head, 5,

during the folding operation. The plun erhead, 5, is mounted uponthelower on of a toothed slide-rack, 9, which is enga ed by a pinion,10, fixed upon the same sha t with a pinion, 11, adapted to be engagedby a toothed rack on the crank-rod, 12, connected with a crank-disk,4-6, operated in a manner hereinafter described, whereby areciprocatingvertical movement is imparted to the plunger-head 5. As theplunger-head, 5, de-

scends through theopening, 4, in the bed-' plate, the bottom of the boxis clamped be tween said plunger-head and the yielding bed, 7, and theblank is drawn down within the aperture, 4:, the walls of which serve toupturn the side-portions of the blank and partly fold the same'toapproximately the cross-sectional form shown in Fig. 8. A pair ofside-wings or flaps, 14, are thus formed on each side of the pail, whichwings require to be folded in from the position shown in Fig. 8 to thatshown in Fig. 9, so that the wings of each pair shall lap each other.This is accomplished toward the latter part of the descending movementof the plunger-head, 5, by means of two airs of oscillatory arms, 15,one of each pair being mounted upon a rock-shaft, 16, and the ot er ofeach pair upon a parallel rock shaft, 17, which rock-shafts have fixedthereon, respectively, rocker-arms, 18, which project into thepath ofthe descending yielding bed 7. The final descending pail therefrom.

In adapting the machine for automatically attaching the wire bails tothe pails, I provide a carrier and holder for the bail in the form of aslide, 19, reciprocatory in slideways, 20, on the bed-plate, and havinga pair of arms, 22, adapted to freely receive therebetween the foldedpail, the body of theslide and said arms being formed with seats toreceive a wire bail, 90, which can be placed thereon by hand; The seatsfor the ends of the bail on the arms, 22, are undercut at, 21, so as tooverhang the ends of the bail. Suitable means which will be presentlydescribed are provided for automatically imparting to the slide, 19,inward and outward movements at proper times.

The inward movement of the slide, 19, is so timed that the bail-ends arebrought o-pposite the lapping portions of the sidewings, 14, on therespective sides of the box upon the completion of the folding of saidside-wings, and when thus located each of said bail-ends is engaged by aplunger, 23, which drives the end of the bail through the lappingside-wings and into an opening, 24, in a stationary upright folder, 25,which cotiperates with the plunger-head to fold upward the side-walls ofthe body of the pail. Each of the upright folders, 25, is supported onlyat its lower end and has its upper end projecting freely into theaperture in the bed with a free space on all sides between its free endand the walls of said wedge-shaped member, 31, in fixed relation to theplunger, 23, so that as the plunger, 23, moves inward to force thebail-end through the side-wings of the pail, the cam, 31,'will be forcedagainst the stud, 30, caus-. ing a rocking movement of the rock-shaft,28, whereby the clenching-arm, 26, is moved across the path of theinserted end of the bail, serving to clench the same as above described.

The thickness of the clenching-arm, 26, and the upright folder, 25, issufiicient to prevent the end of the bail from penetrating theside-wall, 32, of the body of the pail, as will be seen'in Fig. 9. Thestock itself of the lapping side-wings affords sufficient support to thebail-wire to enable the elenchmg-arm, 26, to bend the end of thebailwire to hook-form as above described.

When the bailing operation has been completed, the lungers, 23, withtheir wedges, 31, are with rawn, permitting the clenchingarm to bereturned to its initial position by means of the coil-spring, 33; theslide, 19, is moved back to its outermost position, and theplunger-head, 5, is raised, carr ing upward with it the folded-and-bailed pail. As the rocker-arms, 18, are relieved from pressure by therising of the bed, 7, the Wingfolders are rocked back by means of'acoilspring, 34, which connects together a pair of ocker-arms, 35, fixedupon the respective root-shafts 16 and 17.

As a means for accomplishing the necessary movements of the slide, 19,and plunger, 23, in proper time-relation with the descending andascending motions of the plungerhead, 5, I provide connections wherebyall of said mechanisms are driven from a common shaft 37. A pinion, 38,on the shaft, 37, engages a gear-wheel, 39, on a shaft, 40, rotativelymounted in bearings, respectively on the bed of the machine, and on theupper end of the stationary post 47. The gearwheel, 39, meshes with agear-wheel, 41, which runs loosely on a shaft, 42, which shaft isrotatively mounted in bearings on the frame of the machine.

In fixed relation to the gear-wheel, 41, is *one member, 43, of anintermittent clutch, the other member, 44, of which is feathered uponthe. shaft, 42, and is forced into engagement with the clutch-member,43, by

means of a coil-spring, 45. When the clutch-member, 44, is held inengagement with the clutch-member, 43. by means of said coil-spring, therotary movement of'the gear, 41, will be transmitted to the shaft, 42,

upon the end of which shaft, 42, is fixed a crank-disk, 46, with whichis connected the crank-rod 12. The movable clutch-member, 44, is atcertaintimes forced out of engage ment with the clutch-member, 43, bymeans of a lever, 50, fulcrumed at, 51, upon a fixed bracket, 52, andhaving on its upper end a yoke, 53, engageable with the hub of theclutch-member, 44, and on its lower end a stud or cam-follower, 55,adapted to be engaged by a cam, 56, fixed upon the shaft 40. The cam,56, is so shaped that upon the completion of the downward movement ofthe plunger-head, 5, the clutch is held open to permit the plunger-head,5, to remain stationary during the bailing operation. A verticalrock-shaft, 57, is mounted at its lower end in a bracket, 58, projectingfrom the post, 17, and at its upper end in a bracket, 59, projectingfrom the base of the machine, said shaft having fixed thereon arocker-arm, 60, upon the end of which is a cam-follower, 61, whichoccupies. a camgroove, 62, in a cam-wheel, 63, fixed upon the shaft, 40,whereby'rocking movements are imparted to said shaft 57. Arockerarm-,.64, on the upper end of the shaft, 57, is connected by ashort link, 65, with one end of a link, 66, the other end of which isconnected with a lever, 67,'fulcrumed at, 68, upon the underside of thebed-plate of the machine, and having a slotted end adapted to engage astud or pin, 69, fixed to one of the plungers 23. The link, 66, is alsoconnected with one end of a lever, 70, fulcrumed at, 71, upon theunderside of the bed-plate, and having its other end connected by alink, '7 2, with one end of a lever, 73, pivotally connected at, 74,with a slide, 75, movable in a slideway on the underside ofthe,bed-plate. The other end of the lever, 73, is connected with one endof a lever, 76, fulcrumed at, 77, on the underside of the bed-plate, andhaving a slotted end, 78, adapted'to engage a stud or pin, 79, fixed tothe other plunger 28. The lever, '73, being mounted upon the slide, 75,a movement of the link, 72, will impart a bodily movement not only tothe slide, 75, but to the lever, 73, which is however free to rock uponits pivot, 74, to accommodate itself to the arc of movement of the endof lever, 76, with which it is connected. A 'pair of camshaped plates,80 and 81, are mountedupon the slide,-7 5, in position to at certaintimes engage one arm of an angle-lever, 82, fulcrumed at, 83, upon theunderside of the bed-plate, and having its other arm slotted and adapted:to engage a stud or pin, 84,

fixed to the slide, 19-, which stud or pin, 84,

projects down through a slot, 85, in the bedplate. j

The arms of the several levers are so proportioned as to accomplish theseveral movements in the order above described, and the cam-shapedplates, 80 and 81, are so located as to provide lost-motion in theoperation of the lever, 82, at the beginning of the inward movement ofthe slide, 19, to allow a suiiicient interval for the folding operationbefore the bail is moved into position for the bailing operation, and atthe beginning of the outward or return movement of the slide, 19, toallow the necessary interval for the withdrawal of the plungers, 23,before the return movement of the slide begins.

I make no claim herein to the features above shown and described whichpertain to the bailing-mechanism, as such features form the subjectmatter of an application filed by me, December 8, 1911, Ser. No.664,608, as a division of the present application.
